What does constitute a derby in sport? Hull v Hull KR is certainly a derby. As is Leeds v Hunslet. But does Saints/Wigan really count as a derby? Or Leeds/Bradford for that matter?What about Bradford/Keighley? I've cited Cas/Fev. The grounds are probably only 3 miles apart and they are both in Wakefield met - but Cas is a town and so is Fev. And what about Wakey? What about Batley, Dewsbury and Huddersfield - all in Kirklees MDC? Swinton and Salford would surely count wouldn't they?Obviously in soccer Wednesday/United is a derby. Presumably Villa v City, but what about West Brom? Arsenal/Spurs? what about the other London sides? And Man City and Man U are actually in different towns, although they're both called Manchester. Liverpool/Everton is certainly a derby - you can see one ground from the other. So what do we in RL call a derby? And has there ever been a definitive definition of one?

Oh FFS how many times do people have to post the dictionary definition.

"local derby a sporting event between teams from the same area"

Note the word area, not city, not town, not village, not country, not continent, not planet but area.
